SYS Passive Preamp Volume Control and 2-Input Switch (Black)

Très bon produit

車のオーディオに使用してます 純正や社外品のオーディオ（ヘッドユニット）を使用せずに、ストリーミングオーディオやネットフリックスの音声をアクティブクロスオーバーネットワーク、パワーアンプを経由し、スピーカーから出力するために、アッテネーター兼セレクターとして購入しました。 確かにいわゆるプリアンプ的な存在ではありますが、電源レスで1ミリも信号の増幅をしていないのにパッシブという名をつけたところでアンプを名乗っていいのか甚だ疑問ですが、 こまけーことを言うタイプの人はたぶん買わない商品なので言いません（言ってる）。 アメリカよりDHLで届いたので、為替や送料の影響はあるにせよ、価格に対してもう少し質感が欲しいところです。

I use this to switch between bookshelf speakers powered by a Marantz 1060 integrated receiver, and floor speakers powered by a separate power amp, with the Marantz as the preamp. This makes it impossible to run both speakers at the same time, which would damage my equipment. It's a little pricey comparatively, but not really, because it's very well made and will obviously last as long as my other high quality equipment. It looks good and feels solid, and there is no noise or interference at all...like it should be.

Works perfect. Made in the USA. I only say that because I've already had a couple of these from cheap companies and they didn't work and the quality was for crap. If you want to buy quality electronics like this such as RCA splitters and selectors and all kinds of stuff, you should definitely take a close look at this company because it's actually quality products. Thank you for that.

This is a non-powered, passive RCA selector switch. We are currently using it to switch between an older 5.1 audio receiver and a 2-channel stereo Integrated amplfier, to a single subwoofer. This provides an easier way to adjust amplifier gain and to switch audio supply sources without unhooking cables. We are not sure how affects overall sound quality. As long as the internal switching connections and conductors are good it should just pass the signal as intended. So far we are satisfied with this product. (Paired with a modi 3e DAC, from the same company)
